Astronaut Scott Kelly hosts a Reddit Q&A from space at 4PM ET

You may have seen some interesting Reddit Q&A sessions in your day, but you probably haven't seen one like this. NASA astronaut Scott Kelly is hosting an Ask Me Anything session at 4PM Eastern today (January 23rd)... from space. That's right -- you can learn what it's like to live aboard the International Space Station from someone who's there right now. Suffice it to say there are plenty of questions: how does long-term residency in space affect you, physically and psychologically? What's the coolest thing you've seen while orbiting Earth? And what's it like to grow flowers in space? There's no guarantee that Kelly can answer every burning question, but it'll be worth participating just to get his unique perspective.
